What is an inductive sensor? The basic structure, characteristics, working principle, application, classification, testing circuit, common fault phenomena and causes of inductive sensors 2

3、 Working principle:

The working principle of inductive sensors is based on the law of electromagnetic induction. When the current in the coil changes, a magnetic field is generated, and the change in magnetic field causes a change in the inductance in the coil. Inductive sensors measure changes in inductance in coils to obtain changes in inductance values, which are then converted into electrical signals or other forms of output signals.diode

4、 Application:

Inductive sensors are widely used in industrial automation, aerospace, automotive electronics, medical equipment and other fields. Specific applications include displacement measurement, pressure measurement, flow measurement, mechanical measurement, etc.diode

5、 Category:

According to the working principle and structural characteristics, inductive sensors can be divided into the following categories:

1. Inductive sensor: Inductive sensor is a sensor that uses changes in inductance to measure physical quantities. Common inductive sensors include coil sensors, transformer sensors, etc.

2. Magnetic resistance sensor: A magnetic resistance sensor is a sensor that uses changes in magnetic resistance to measure physical quantities. Common magnetic resistance sensors include magnetic resistance change sensors, Hall sensors, etc.diode

3. Capacitive sensor: A capacitive sensor is a sensor that uses changes in capacitance to measure physical quantities. Common capacitive sensors include capacitive change sensors, capacitive touch sensors, etc.diode

4. Resistive capacitive sensor: A resistive capacitive sensor is a sensor that measures physical quantities using changes in resistance and capacitance. Common resistive capacitive sensors include resistive capacitive change sensors, etc.
